Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.


Characterisation of the Schizosaccharomyces pombe rad4/cut5 mutant phenotypes: dissection of DNA replication and G2 checkpoint control function.

McFarlane RJ, Carr AM, Price C

Mutation of the essential Schizosaccharomyces pombe rad4/cut5 gene causes sensitivity to UV and ionising radiation at the permissive temperature whilst at the restrictive temperature cells fail to undergo DNA replication but still attempt mitosis owing to a defective S-phase checkpoint response. Many mutations in genes encoding DNA replication proteins also abolish checkpoint responses, possibly because the replication machinery is a ... [more]
